AI Technical Summary

Benefits of technology

The patent describes an elongated seal used to seal between two parts. The seal is made up of multiple elongated members that are attached to the outer surface of the seal to help position it correctly. The seal can be used to seal along the edge of a component or to provide a fire boundary. The elongated members may have a pulling tool attachment and may be more or less flexible at different points along their length to make gripping and positioning easier. The sealing arrangement may also help prevent the seal from being urged out of position during installation. Overall, this sealing arrangement provides a reliable and effective way to seal components.

Problems solved by technology

Seals can be safety critical, for example where transference of a gas or liquid across the seal would cause a safety incident.
However once the components are installed, the seal is harder to access.
If the seal contributes to a fully enclosed space, it is possible that after the components are installed next to each other there is no access to the seal, or only limited access to the seal.

Embodiment Construction

[0053]With reference to FIG. 1, a gas turbine engine is generally indicated at 10, having a principal and rotational axis 11. The engine 10 comprises, in axial flow series, an air intake 12, a propulsive fan 13, an intermediate pressure compressor 14, a high-pressure compressor 15, combustion equipment 16, a high-pressure turbine 17, an intermediate pressure turbine 18, a low-pressure turbine 19 and an exhaust nozzle 20. A nacelle 21 generally surrounds the engine 10 and defines both the intake 12 and the exhaust nozzle 20. A core fairing 24 surrounds the core. The core fairing 24 defines a fire boundary.

[0054]The gas turbine engine 10 works in the conventional manner so that air entering the intake 12 is accelerated by the fan 13 to produce two air flows: a first air flow into the intermediate pressure compressor 14 and a second air flow which passes through a bypass duct 22 to provide propulsive thrust. The intermediate pressure compressor 14 compresses the air flow directed into ...

Abstract

An elongate compressible seal is provided for sealing between a first component and a second component, the seal comprising a plurality of elongate members each attached at a first end to an outer surface of the seal for aiding positioning of the seal.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is based upon and claims the benefit of priority from British Patent Application Number 1814484.0[0002]filed 06 Sep. 2018, the entire contents of which are incorporated by reference.BACKGROUNDTechnical Field[0003]The present disclosure concerns a seal, a sealing arrangement and a method of forming a sealing arrangement.Description of the Related Art[0004]Seals between two components are generally flexible members that contact portions of each component in a compression fit. The flexibility of the seal and the compression fit ensure that the seal contacts and seals along the entire sealing portions of each component.[0005]Seals can be safety critical, for example where transference of a gas or liquid across the seal would cause a safety incident. Seals may also form part of a fire boundary. In these situations it is of greater importance that the seal is robust and adequately seals along the length of the seal.[0006]Howeve...
